Hugh Possingham, chief scientist of the NGO The Nature Conservancy, who presented in Colombia this week a controversial mathematical formula that measures the cost-benefit of saving different species, in order to decide which should be given priority. EFE/NGO The Nature Conservancy

Math has already been used effectively in defining protected areas in places with productive activities in 150 countries over the past 15 years. The best example of that application is Australia's Great Barrier Reef, where a software called Marxan permitted the expansion of protected areas from 5 percent to 35 percent while preserving species and improving fishing.

[OP-ED]: Deficits forever?

 07/20/2017 - 12:15
The federal budget remains badly out of whack, even though we are near or at “full employment” (June unemployment rate: 4.4 percent). We cannot afford tax cuts; we need tax increases.

House Republicans, who are now deliberating the government’s 2018 budget, pledge to eliminate deficits within a decade. Well, good luck with that. It must be obvious that chronic deficits reflect a basic political impasse that can be broken only if majorities in Congress do things they’ve refused to do: trim Social Security benefits; raise taxes significantly; control health spending. There is a giant mismatch between what Americans want from government and what they’ll pay for with taxes.
